Elton John has been receiving congratulatory notes from around Twitter-Wood this week, thanks to the birth of his son Zachary. Neil Patrick Harris even wants to pencil in some play dates as soon as possible.

In other tweets, Olivia Wilde graciously accepted some congrats from Chris Kattan, while John Cusack attempted to clear up some confusion about his travels among his friends. And I wouldn't recommend doing to your iPhone what Penn Jillette put his through, but he seems sold on the product's ability to withstand a two-story fall. Find out why -- and who wants to get married in a tribute to Hugh Hefner -- after the jump.
